BRICK-KILN CONSTRUCTION.

y Specification of Letters Patent.

, Patented May 4, 1915.

Application led October 18, 1912. Serial No. 726,472. Y

T0 all 'wh-0m it may concern.'

Be it known that I, KARL W. KLosE, a citizen of the United States, residing at Seneca, in the county of Nemeha, in the State of Kansas, have invented certain new and useful Improvements in VBrick-Kiln economical in operation and in which `the entire plant is centered in one building thus reducing the matter of the transportation of brick to the minimum.

In the form shown my invention comprises the combination of a specially designed open-top, continuous kiln and a superstructure providing drying floors so arranged that all of the heat radiated by the fire chambers, the heat stored up in the burned brick and the heat of the smoke gases may b e used for drying purposes.

` Another object of my invention is to provide a conveying system which facilitates the transportation of the material from drying floor to the lire chambers of the kiln and from kiln to a railway car or stock pile. Y

My open-top continuous kiln consists of two parallel underground channels which' are divided by the main smoke feet flue and connected at both ends with each other by flues. y

This construction hereinafter briefly referred to is shown described and claimed in my copending application No. 858,9261iled August 27, 1914.

This invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specilication, pointed out in the claims and illustrated in the accompanying drawings which form a part of said specification and in which- 4 Figure 1 is an horizontal section taken on line 1-1 of Fig. 2. Fig. 2 is a section through they brick kiln construction in end elevation and is taken on line 2 2 of Fig. 1.

Fig. 3 is a section throughthe brick kiln p construction in sidev elevation. K

Like` reference characters indicate correspending parts throughout the several v1ews.

The superstructure comprises side walls 1-1, a front wall 2 and a rear wall 3 and a roof l- :over all. ,The structure forms a housing over the kiln proper and is supported by suitable brace beams as shown and is provided with a drier floor 5 for the green brick. To the joists of the vfloor 5 an I-beam track 6 is secured which is U-shaped having its ends adjacent the rear wall 3 and its connecting portion or base adjacent the front wall 2. BeneathV the floor f5 is a large smoke flue 7 which comprises four branches lying adjacent the floor as shown, a branch lying parallel with each wall of the structure and this smoke flue 7 is fed by a feed flue 8 that connects with the lire chambers 9, 9 which are parallel channels sunk in the ground and each provided with lateral walls 10, 10.

11 isa fan, which as shown is suitably supported above the drying floor and which is connected by a pipe lead 12 with the large smoke flue 7. The fan is provided with an outlet Huev 13 extending out through the roof 1 of the kiln. Y

In order to use the two parallel chambers as a continuous kiln, I connect one chamber with another at each end by flues 19, extending through the intermediate wall 10. In each of the side walls 10 of the fire chambers are centrally opening flues 15-15. In the two adjacent walls 10A forming the main 4 smoke 'flue 14, these fines open upwardly at the top of the wall and may be connected with the main smoke iiue 14 by means of U-shaped pipes 16. These flues 1'5-15 in the outer side walls open upwardly at the top of the ground and are adapted to be connected with subterranean passages 20, 21 and 22 running parallel with the side walls 10, by means of similar U-shaped pipes 16, which may connect the upper ends of the flues 15 with upwardly extending openings 23 of each of these lues. The ends of inner passages 20 are in communication with flues 20% extending transversely across each end of the kiln and parallel with the ends thereof. Other passages 21 and 22 may be connected at their ends by means of U- sha'ped pipes 16, through openings 23, with openings 26 of similar passages 24 and 25, also extending parallel with the ends of the kiln. In so using the kiln, one of the chambers 9, is entirely filled with brick and the other' partially filled, leaving a space extending transversely of the kiln, from one side of which bricks are being taken out and on the other side of which bricks are being placed in position to be burned. The loosely set brick in the kilns form a circuit through which the draft may flow, passing into the side of the space from which the bricks are being taken out, through the burned ware to the fire, passing to the fire and then back nearly to the side of the space where the green ware is being put in. The draft passes through the flues 19 in this course and is led upwardly from the green ware through the flues 15, to the main flue through U-shaped pipes properly positioned. By suitably arranging the U-shaped pipes 16 and by closing the openings 23, not covered by a pipe 16, with removable plugs, not shown, a part of the heated gases may be conveyed from the fire through these subterranean passages 20 and 20il to portions of the green brick. Heated gases of lower temperatures may be taken from other parts of the kiln, through the passages 21 and 22 and brought to any desired portion of the fire chamber' through either of the passages 24 and 25. 1n this manner the temperature within the kiln may be so regulated that injury to the bricks by heating and by water smoking while under operation, may be prevented.

In the interior of the kiln housing an inclined track 27 is disposed with one end resting in a pit 28 in the ground and the other bolted to beams V29 which beams are suitably supported by the kiln brace beams and which also carry the axle 30 of a pulley 31 over which a cable 32 runs that is connected to an elevator 33 adapted to run over the inclined track, the other end of the cable p carrying a counterbalance weight 34; the

elevator 33 being provided with a platform 35. To the beams 29 uprights 36 are sef cured which pivotally carry a lever 37 provided with a flexible hand grip 38 which may be used to bring the lever 37 down upon the cable 32 to serve as a brake shoe upon the same as it works over the pulley 31.

Operation Y:V The fresh brick when brought to the kiln are piled upon the drying floor 5 and left there to dry preparatory to being burned. A great deal of heat rises from the fires burning in the fire chambers 9 and much of it will seep through the Hoor 5 to dry the brick and smoke and heat will pass through the flues 15 and pipes 16 into the smoke area way l-l and u 3 through the feed Hue 8 into the large iiuesl? beneath the iioor 5 and the fiues 7 will radiate a great deal of heat to dry the green brick.

When the vbrick have been sufciently dried to be burnt they may be loaded upon a suitable truck or wheelbarrow taken to the elevator 33 which is a gravity elevator and may be then lowered to the ground under the I-beam line. The hoist is then used to convey them from the elevator and lower them into the proper position in the kiln. Heat from the fires will be conveyed through the flues 15 from the lire chambers into the vicinity ofthe green brick and the continuous open-top fire chambers will radiate eX- cessive heat directly. The subterranean passages 20, 21 and 22 with their fiues and the like passages 20a, 25 and 26 will tend t0 equalize the temperaturek within the kiln and to so regulate the heat that it will not injure the brick under operation. When the pipes 16 are in position the draft from the draft fan will draw a great deal of smoke and heat up through the smoke flues 7 and connections. When the brick are burnt they are placed upon the ordinary pallet which is picked up by the trolley (not shown) that runs upon the I-beains and carried either to the railway car or stock pile.

Wha-t is claimed is 1. The combination of an open top kiln, a superstructure covering the kiln and having a drying floor above the kiln, said kiln having a main smoke Hue, flues adjacent the drying floor connected with the main smoke flue and a blower for producing a draft through said smoke flues.

2. Thecombination of an open top kiln, a housing covering the kiln and having a drying floor above the kiln, and a trolley track secured to said, drying floor and extending over the kiln.

3. The combination with a continuous kiln comprising two parallel lire chambers below ground having open tops, of a housing, a dry floor within the housing above the kiln, and a trackway adjacent the under, side of the drying floor and extending over the fire chamber.

il. The combination with a continuous kiln having a fire chamber below ground, of a superstructure covering the chamber having its side walls spaced from the fire chamber, a drying floor within the housing above the fire chamber, and a lowering device conveying brick from the ldrying floor ing floor, a trolley track extending over the ture in the' presence of two subscribing Witkiln from a point adjacent one of the Walls, nesses. and a lowering device Within the kiln adapted to stand in its lower position beneath a portion of the trolley track.
